Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide the cable of a kind of abrasion extruding that can reduce cable core.

For achieving the above object, this utility model provides following technical scheme: a kind of cable, include cable core, inner sheath, armor, oversheath from inside to outside, described cable core comprises conductor, fire-resistant wrapping tape, crosslinked polyetylene insulated layer from inside to outside, described conductor includes a leading body and four auxiliary-conductors, is provided with division board, described leading body is arranged with separation sleeve between described auxiliary-conductor, the side of described division board is fixing with inner sheath to be connected, and opposite side is fixing with separation sleeve to be connected.

By adopting technique scheme; leading body is circumferentially with four auxiliary-conductors; it is symmetrical arranged conductor and makes cable conductor uniform force when use procedure is subject to external force; when cable uses; between cable core can because of cable bend or Exterior cable by external force time and produce friction and Extrusion; therefore division board is set between cable core and can avoid producing between cable core abrasion; owing to division board and inner protective layer are fixed; thus also can protect cable core not by external compression when cable bend, thus the abrasion extruding reduced between cable core.

This utility model is further arranged to: being cased with insect protected protective layer outside described oversheath, the outside of described insect protected protective layer scribbles anti-corrosion flame retardant coating.

By adopting technique scheme; general cable can be subject to gnawing of Mus ant; thus destroying the protective layer of cable; therefore it is cased with, in the outside of cable jacket, the protective layer that rat-and-ant proof is gnawed; cable is avoided to be gnawed by Mus ant; affect the use of cable; the several functions layers such as flame retardant coating, anticorrosive coat, water blocking layer it are cased with to protect cable core at Exterior cable; but increasing of the number of plies can make cable weight increase; use inconvenience; therefore outside insect protected protective layer, scribble anti-corrosion flame retardant coating, improve cable-flame retardant, anti-corrosive properties.

This utility model is further arranged to: in described division board and separation sleeve, outside is equipped with wearing layer, and described wearing layer is made up of toughness reinforcing aluminium sesquioxide material.

By adopting technique scheme, division board and separation sleeve arrange wearing layer and can avoid the friction between division board and separation sleeve and cable core, thus reducing the abrasion of cable core, toughness reinforcing aluminium sesquioxide material has the advantages such as wear-resistant, corrosion-resistant, high temperature resistant, high intensity, high rigidity.

This utility model is further arranged to: be provided with rubber layer between described crosslinked polyetylene insulated layer and division board, separation sleeve.

By adopting technique scheme, owing to rubber has excellent resilience, insulating properties, therefore rubber layer can produce deformation when cable is squeezed, and removes resilient after external force, thus ensureing that the structure of cable conductor is not damaged, also avoid the friction that contacts with each other between cable core.

Compared with prior art, this utility model has the advantages that arranging division board reduces the abrasion extruding of cable core, improves the service life of cable.
